This book will show you how to create realistic architectural models in  Blender. Blender is an open-source 3D animation program released as free  software. It can be used for modeling, texturing, skinning, animating,  and so on. It runs on all the important operating systems (including  Windows, Mac, and Linux). You can create natural scenery, landscapes,  plants, various weather conditions, environmental factors, building  materials such as wood, metal, brick, and more. You will also learn how  to add people to different scenes as well as other objects to an already  existing photograph or a video making it easier to increase its  realism.
